Detailed Description
Although a Bipolar Capacitor Auxiliary Battery (BCAB) for a battery system of a battery electric vehicle is described below, the bipolar capacitor auxiliary battery may be used in hybrid vehicles or other vehicle and/or non-vehicle applications.
A capacitor-assisted battery (CAB) includes a capacitor connected in parallel with a battery, such as a lithium-ion battery (LIB). CAB may be used in high power output applications up to about 4V. CAB currently uses relatively low voltage chemicals such as lithium phosphate (LFP)/graphite (Gr) and Activated Carbon (AC). The use of CAB in higher voltage designs above about 4.25V is limited by the capacitor in CAB, which has low stability at high voltages and generates gas (especially when subjected to both high temperatures and high voltages).
The Bipolar Capacitor Auxiliary Battery (BCAB) according to the present disclosure improves stability of the CAB and expands its use to high voltage chemical systems, which have longer cycle life and enhanced power output compared to LIB without changing the cell chemistry.
The BCAB according to the present disclosure combines a bipolar capacitor and a lithium ion battery. Two or more capacitors are connected in series and then connected in parallel to the lithium ion battery. The BCAB according to the present disclosure improves electrochemical stability of the CAB and expands the use of CAB at higher voltages.
In CAB, a capacitor and LIB are connected in parallel in a battery cell (battery cell), such as a pouch-type battery cell. In this configuration, Vcell = VC = VLIB . The stability window of the capacitor is narrower than LIB. For example, if VC < 4.0V, LIB cannot employ high voltage systems greater than or equal to 4V, such as NCM811/Gr or LiNi0.5 Mn1.5 O4 /Gr。
To address this situation, the voltage of the LIB may be limited (which reduces the energy density), the LIB chemistry may be limited (which reduces the energy density), and/or a complex control system with switches may be used to control the voltage across the capacitor (which increases cost and complexity).
In BCAB, N capacitors are connected in series and then connected in parallel to LIB. When n=2 capacitors are used, Vcell =2×VC = VLIB . The sum of the voltages of the two or more capacitors is equal to the voltage of the LIB. For example only, a LIB with lithium nickel cobalt manganese oxide (NCM)/Gr has a voltage of about 4.4V. When 2 capacitors are connected in series to the LIB, each capacitor operates below about 2.2V, which is a safe voltage. For LIB with Lithium Nickel Manganese Oxide (LNMO)/Gr, the voltage is-5V and the voltage of each capacitor is 2.5V, which is still a safe voltage. As can be appreciated, BCABs according to the present disclosure causeEnabling high voltage use of CAB, enabling high voltage LIB chemistry, improving energy density, and avoiding the use of switches.

In some examples, thebarrier material 20 may be used to prevent exposure and/or mixing of the electrolyte. Thebarrier material 20 may extend over the exposed outer surface of thebipolar capacitor 12 or be limited to the exposed edges of the separator S of thebipolar capacitor 12.
In FIG. 2, theBCAB 10 includes N serially connected capacitors, providing VC1 、VC2 V. andCN (where N is an integer greater than one).

The preceding description is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses. The broad teachings of the disclosure can be implemented in a variety of forms. Therefore, while this disclosure includes particular examples, the true scope of the disclosure should not be so limited since other modifications will become apparent upon a study of the drawings, the specification, and the appended claims. It should be understood that one or more steps within a method may be performed in a different order (or simultaneously) without altering the principles of the present disclosure. Moreover, although each of the embodiments is described above as having certain features, any one or more of those features described with respect to any embodiment of the invention may be implemented in and/or combined with the features of any of the other embodiments, even if the combination is not explicitly described. In other words, the described embodiments are not mutually exclusive, and permutations of one or more embodiments with each other remain within the scope of this disclosure.
Various terms are used to describe the spatial and functional relationships between elements (e.g., between modules, circuit elements, semiconductor layers, etc.), including "connected," joined, "" coupled, "" abutting, "" next, "" on top, "" above, "" below, "and" disposed. Unless specifically stated as "direct", when a relationship between a first and second element is stated in the above disclosure, the relationship may be a direct relationship where no other intermediate element exists between the first and second elements, but may also be an indirect relationship where one or more intermediate elements exist (spatially or functionally) between the first and second elements. As used herein, at least one of the phrases A, B and C should be construed to mean logic (a OR B OR C) using a non-exclusive logical OR (OR), and should not be construed to mean "at least one of a, at least one of B, and at least one of C".
In the drawings, the direction of the arrows, as indicated by the arrows, generally represents the flow of information (such as data or instructions) of interest illustrated. For example, when element a and element B exchange various information, but the information transmitted from element a to element B is related to illustration, an arrow may point from element a to element B. The unidirectional arrow does not imply that no other information is transmitted from element B to element a. Further, for information transmitted from element a to element B, element B may transmit a request for the information or a reception acknowledgement for the information to element a.
